lMPROVllM-NT IN APPARATUS FOR EVAPORATING SACCHARINE JUICES.

Specification forming part of Letters Patent No. 34,991, (lated April 15, 1862.'

To all whom it ma/y concern:

Be it known that I, CHESTER D. STEVENS,

of Mendota, in the county of La Salle and State of Illinois, have invented a' new and Improved Evaporating Apparatus for Boiling` and 4Reducing Sugar-Cane Juice; 4and I do. .hereby declare the following to be a full, clear,

and exact description of the same, reference being had to the annexed drawings, making part of this specification, in which- VFigure 3 is a top view thereof; Fig. 2, a

. vertical longitudinal section on the line K K,

and Fig. 1 a side elevation.

The object of my invention is to economize fuel inthe reduction of sugarcane juiceto sirup by a novel application of steam to that purpose. l

The followingdescription of my invention will enable any one skilled in thearts to which it appertains to make and use'the same.

Like letters of reference represent corresponding parts of the different figures of the.

drawings referred to.

C is an ordina ry steam-boiler for the purposeofgeneratiug the steam. Over this boiler pan, B, is arranged, ign which the juice is first boiled and skimmed, and which is fitted with a series of steam-tight pipes, X X and Y Y,which pipes communicate with the boiler reducing-pan shown in the drawings; but there may be two or more arranged in the It is fitted with a series O f steam-tight There is but one same relation 'to the boilinglpan andl steamboiler.- These pans may be made`in any suitable form and of any suitable material, and

they may bel fitted with any convenient ar rangement of pipes, which should, however, be provided with blow-cocks, astJ and G,.to let out the air when the steam is letin.. Now, when the steam is let inthe pip'es condensation com1nences,which, if there were'no nieans of issue, would soon fill them with water of condensation, thus stoppingr the process of evapo' ration and reduction, for 'the condense-water f would soon become a's cold as the contents of the pans; and if the pans where arranged below the boiler or on the same horizontal plane with it 4the water of condensation would have tobe blown or drawn outof the pipes, whichwould occasion a loss of heat, and consequently of -fuel equal to the amount o fv heat contained in the water so drawn or blown gout. this loss of heat by blowing out the condense water, andthe obstruction ofthe process resulting from the-choking of the pipes with it, I arrange all the pans above the boiler and the pipesin them -so as to incline a little toward the pipes F and E, communicating with 'the boiler. By these means the water of condensation falls back in'tothe boiler as fast as it is formed, thus saving the fuel and increasing the efficiency of the apparatus by :mak-ing 1 the entire surface of the pipes effective.

Having now described the manner of con- Struet'ing and operating my invention, I claim and desire to secure'by -Letters Patent-'- The arrangement and-construction of the boiling and evaporating panslin relation to each other and t th`e steam-boiler C, substan-v 4tially in the nianner described". i
